Describes the nature of a clinical study. Types include:
- Observational study — observes people and measures outcomes without affecting results.
- Interventional study (clinical trial) — studies new tests, treatments, drugs, surgical procedures or devices.
- Medical records research — uses historical information collected from medical records of large groups of people to study how diseases progress and which treatments and surgeries work best.
During the early phases (phases 1 and 2), researchers assess safety, side effects, optimal dosages and risks/benefits. In the later phase (phase 3), researchers study whether the treatment works better than the current standard therapy. They also compare the safety of the new treatment with that of current treatments. Phase 3 trials include large numbers of people to make sure that the result is valid. There are also less common very early (phase 0) and later (phase 4) phases. Phase 0 trials are small trials that help researchers decide if a new agent should be tested in a phase 1 trial. Phase 4 trials look at long-term safety and effectiveness, after a new treatment has been approved and is on the market.

About this study
RATIONALE: Sunitinib malate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth or by blocking blood flow to the tumor. Drugs used in chemotherapy, such as gemcitabine hydrochloride, work in different ways to stop the growth or tumor cells, either by killing the cells or by stopping them from dividing. It is not yet known whether giving sunitinib malate and gemcitabine hydrochloride together is more effective than sunitinib malate alone in treating patients with kidney cancer.
PURPOSE: This randomized phase II clinical trial is studying giving sunitinib malate together with or without gemcitabine hydrochloride to see how well they work in treating patients with advanced kidney cancer that cannot be removed by surgery.
